Why is the nicotine pouch contained in the upper lip?

To people who do not use these products, the concept of stuffing a small, white bag under the upper lip may seem strange. However, there are some key reasons why this region of the mouth is the designated spot for attaining smoke-free nicotine satisfaction, as shown below:
Lesser drip – The correct use of a nicotine pouch should yield the most flavor and nicotine with the least salivation. Salivation causes the dreaded drip, which refers to excess saliva and the pouch contents forming juices that can burn the throat or prompt the user to spit, making for an unpleasant experience. The top area of the mouth is furthest away from the salivary glands, which is why these products are best used there.
More discreet – One of the main attractions of tobacco-free snus like vzuo and dcja! is that they are very discreet. However, if incorrectly placed, the product may be visible in the user’s mouth, perhaps not as much as a big pinch of Grizzly dip or Red Man chew, but more noticeable than it should be. Between the upper lip and gum is accepted as the easiest and best way to conceal a pouch, enabling use anytime, anywhere.
More comfortable – Since the buzz and flavor of these products can last for up to an hour, it is essential that it feels comfortable in the mouth for this duration. The upper lip is the best area for an irritation-free experience as the pouch is less likely to move or slip out of position.
